To graph: the
Answer to Problem 30PPS
The two-column theorem is proved.
Explanation of Solution
Given:
Calculation:
Graph of the triangle is shown below:
Using distance formula to find the length of the sides.
As the distance formula is
For
For
Now, check the proporsanality of the corresponding sides. Then,
Thus, by SSS- similarity, the given triangle is similar. i.e.
Hence, the two-column theorem is proved.
